Hi,

I am solving a external CFD simulation over the terrace of building on which Chillers and ODU are placed.

As of now, i am using 3D fan zone condition for the chiller fan & ODU fan. But now i want to create the inlet for the chiller & ODU in the enclosure.

I am using pressure inlet boundary condition for the inlet flow area. To reduce the mesh requirement, i have modelled the Chiller as fluid domain and cut in half.

Top half portion i have labeled as wall and bottom half portion i have provided pressure inlet boundary condition. As the enclosure already make the shadow portion of fluid surface on the wall of Chiller, i am not getting correct results over it. 

for the reference see below image.

The "pressure inlet" should be an interior surface as you can't set an external type boundary on an internal surface. Please post some images from Fluent so we can see what's going on.
